Sorry, I was not able to return to the thread earlier - its fourth of July weekend. WinALDL was written for Win98 and WinY2K also works on XP. If you are running Vista you may run into some file write issues.

A handful of knock counts during acceleration I would say is normal. I think the only way we are getting to the bottom of this is to get some data logging. In TunerPro-RT you can enable data conversion by changing operation function from multiply to use look up table. This should take care of conversion.

This hesitation that you are experiencing could be due to a weak spark. Small hat HEI use external coil which are prone to fail over time. They tend to fail slowly over time, and go out completely when heat soaked. Typical symptoms - loss of power, hesitation, hard hot starts. The only way to verify coil is to have HV scope that can measure HV voltage pattern. Again, before blaming coil I would check all other ignition related parts - all wires, rotor, dizzy hat, and center contact.

Sorry but I do not have any other thoughts at this time. As general rule I do not recommend mindless sensor swapping.
